Pruritic urticarial papules and plaques of pregnancy (also known as polymorphic eruption of pregnancy, or PUPPP) has an incidence of 1/200 pregnancies. The onset of PUPPP is usually in the third trimester. The pruritic, erythematous, papules and plaques are usually first seen in the abdominal striae (stretch marks) and then spread to the chest, trunk, and extremities. The papules and plaques typically spare the palms, soles, face, and mucous membranes. Large vesicles or bullae are uncommon, though pinpoint vesicles may be seen (Fig. 60-1).
